Roaming between access points and RX signal strength

Hi everyone!

Does someone know if the Wi-ME can be set up to avoid roaming among several access points, that is, remain attached to a fixed one or otherwise lost the connection if the signal from that one drops.

And i would also like to know if there is some command to know the current received signal strength and/or link quality. I’ve checked in the command reference manual but don’t see there anything regarding that…

Many thanks,
